Symptoms

Translucent vlan-groups may set the locally-unique bit in a destination MAC address when sending traffic to a pool member/client.

Impact

Traffic handled by translucent vlan-groups may not work properly.

Conditions

On versions earlier than 15.0.0: - Translucent vlan-group is in use. On v15.0.0 and later: -- Translucent vlan-group is in use. -- The connection.vgl2transparent db variable is enabled.

Workaround

On versions earlier than 15.0.0, there is no workaround. -- On version 15.0.0 and later, you can disable the connection.vgl2transparent db variable to mitigate the problem: tmsh modify sys db connection.vgl2transparent value disable Note: connection.vgl2transparent is disabled by default.

Fix Information

None
